Abstract
An optical camera lens assembly comprising seven lenses, where at least one of the first lens to the fourth lens has a negative refractive power; a plurality of spacing elements, comprising a first spacing element disposed on an image-side surface of the first lens and a second spacing element disposed on an image-side surface of the second lens; and a lens barrel, for accommodating the imaging lens group and the plurality of spacing elements; where, radii of curvature of the object-side (R1) and image-side (R2) surfaces of the first lens, and a radius of curvature R3 of an object-side surface of the second lens satisfy: R2/R3>R1/R2>0; and an inner diameter d1s of an object-side surface of the first spacing element, a center thickness CT1 of the first lens, an outer diameter D2m of an image-side surface of the second spacing element, and an air spacing T23 satisfy: 9<d1s/CT1+D2m/T23<26.
